ERP systems success: an empirical analysis of how two organizational stakeholder groups prioritize and evaluate relevant measures
2007
Organizations worldwide are adopting enterprise resource planning (ERP) systems. A number of studies discuss the implementation and success of such systems, but our study of the literature indicates that discussions about ERP systems success from the perspectives of key organizational stakeholders are not easy to come across. This study is designed to fill this gap in research. Using surveys in Finland and Estonia, we obtained empirical data from 66 respondents in 44 diverse, private, industrial organizations. Our objective was to determine whether differences exist between two organizational stakeholder groups, i.e. business managers and IT professionals, concerning how each group believe …
Modeling and querying facts with period timestamps in data warehouses
2019
Abstract In this paper, we study various ways of representing and querying fact data that are time-stamped with a time period in a data warehouse. The main focus is on how to represent the time periods that are associated with the facts in order to support convenient and efficient aggregations over time. We propose three distinct logical models that represent time periods as sets of all time points in a period (instant model), as pairs of start and end time points of a period (period model), and as atomic units that are explicitly stored in a new period dimension (period∗ model). The period dimension is enriched with information about the days of each period, thereby combining the former tw…
Aggregation in Input–Output Tables: How to Select the Best Cluster Linkage
1991
In this paper we try to give a solution to the aggregation problem on working with Input–Output tables. First of all we verify the degree of similarity among the production functions of the industries which aggregate in each sector. Secondly, once we have established the aggregation by using different cluster analysis, we set a number of conditions required to choose the proper linkage method that allows us to characterize the process of aggregation (weighted or unweighted) of the input–output table.
Drivers and dynamic processes for SMEs going global
2006
PurposeMany, if not most, small to medium‐sized enterprises (SMEs) are subject to the impacts of globalisation. This article seeks to explore the extra dimension of challenge to their already difficult environments when they have to venture into the world‐trade system.Design/methodology/approachRecent research undertaken separately by Polish, Italian, Norwegian and UK collaborators examined eight case studies of disparate smaller companies with international operations. This article brings together the common features found, and discusses them in terms of structural drivers and dynamic implications.FindingsResearch findings include the stretching of capabilities in supporting customers in u…
Formulations for an inventory routing problem
2014
In this paper, we present and compare formulations for the inventory routing problem (IRP) where the demand of customers has to be served, over a discrete time horizon, by capacitated vehicles starting and ending their routes at a depot. The objective of the IRP is the minimization of the sum of inventory and transportation costs. The formulations include known and new mathematical programming formulations. Valid inequalities are also presented. The formulations are tested on a large set of benchmark instances. One of the most significant conclusions is that the formulations that use vehicle-indexed variables are superior to the more compact, aggregate formulations.
Deweyan Democracy, Neoliberalism, and Action Research
2019
This article aims to establish a line of continuity between John Dewey's democratic and educational ideals and the practice of action research, to justify that the latter affords an adequate means to enact Dewey's ideals against the destructive challenges that neoliberalism poses to democracy today. This aim involves three ideas that will be developed in three corresponding sections. After the Introduction, the first section analyzes at length the main tenets of Dewey's thoughts about democracy by emphasizing the role of the educational dimension. The article then approaches neoliberalism by focusing on one of its variants, New Public Management, and explains why the latter implies a direct…
IMPLANTACIÓN INTERNACIONAL DE LOS MINORISTAS DE MODA MULTICANAL: CAPACIDADES DINÁMICAS E INCRUSTACIÓN EN LOS MERCADOS
2017
Para estudiar la actividad internacional de las empresas minoristas de moda proponemos un marco que analiza las diferentes dimensiones de 'incrustación' en los mercados exteriores con las capacidades dinámicas. Partiendo de nueve entrevistas en profundidad a directivos de empresas del sector, obtenemos que cada dimensión de incrustación se apoya en diferentes capacidades dinámicas. La social requiere capacidades de construcción de marca que interactúen con las capacidades de gestión del canal y de gestión del conocimiento; la relacional está respaldada por las capacidades de gestión de los canales, mientras que la territorial lo está también por las capacidades de gestión de los canales. To…
Dimensions of Community Assets for Health. A Systematised Review and Meta-Synthesis
2021
Since Aaron Antonovsky’s salutogenesis theory and Morgan and Ziglio’s health assets model were first proposed, there has been a growing concern to define the resources available to the individual and the community to maintain or improve health and well-being. The aim of the present study was to identify the dimensions that characterise community assets for health. To this end, we conducted a systematised review with a meta-synthesis and content analysis of research or projects involving asset mapping in the community. Articles that met our eligibility criteria were: (1) based on the salutogenic approach and (2) described an assets mapping process and among their results, explained what, how…
Business Intelligence Integrated Solutions
2017
Abstract A Business Intelligence solution concerns the simple, real-time access to complete information about the business shown in a relevant format of the report, graphic or dashboard type in order help the taking of strategic decisions regarding the direction in which the company goes. Business Intelligence does not produce data, but uses the data produced by the company’s applications. BI solutions extract their data from ERP (Enterprise Resource Planning), CRM (Customer Relationship Management), HCM (Human Capital Management), and Retail, eCommerce or other databases used in the company.
Relational capital in virtual teams: the role played by trust
2009
The study of social capital has emerged as a key construct in work and organizational contexts. Trust is its relational dimension and it is relevant for teams working in virtual environments. The purpose of our study is to determine whether the relationship between virtuality level (based on the characteristics of the technology used by each group) and three team-effectiveness criteria (group performance, group process satisfaction and group cohesion) is moderated by group trust climate or relational capital (i.e. trust perceptions shared by team members). A laboratory experiment was carried out with groups randomly assigned to two virtuality levels (videoconference and computer-mediated co…
